                <p>Usually the application dictates what standard should be followed and there is
                    no choice other than following the applicable industry standard. </p>
                <p>However, if the usage is strictly internal it is possible to chose any
                    symbology. However for generic usage we would recommends using either Code 39 or
                    Code 128 since they offer great flexibility, supports large character sets and
                    is fairly efficient in terms of space/datasize ratio.</p>
